Luminescence of nano- and macrosized LaPO4:Ce,Tb excited by synchrotron radiation

V. Pankratov, A.I. Popov, A. Kotlov, C. Feldmann
Comparing the luminescence properties of nanosized and macroscopic LaPO4:Ce,Tb powders are performed in wide spectral range using synchrotron radiation. In the present study, LaPO4:Ce,Tb nanopowder was produced by means of a microwave-induced synthesis in ionic liquids, whereas the bulk sample...

Numerical Evidences of Polarization Switching in PMN Type Relaxor Ferroelectrics

E. Klotins, A. I. Popov, V. Pankratov, L. Shirmane, D. Engers
We present a conceptual and computational framework for chemically ordered Pb(Mg 1/3 Nb 2/3 O 3) (PMN) type supercells violating disorder of the host lattice. The effective Hamiltonian is specified by invariance under permutations of supercells and by the dipole-dipole interaction supporting both...

First-principles simulations of the electronic density of states for superionic Ag2CdI4 crystals

S. Velgosh, B. Andriyevsky, I. Karbovnyk, I. Bolesta, O. Bovgyra, W. Ciepluch-Trojanek, I.V. Kityk, A.I. Popov
Energy band dispersion calculations have been performed for Ag2CdI4 superionic within a framework of local density approximation (Perdew–Zunger parameterization) exploiting the first-principles CASTEP computer code. The ab-initio electronic structure simulations were performed for both (I4̅...
